This simple Ruby gem helps you run a loop forever, in a background thread.

```ruby
require 'always'
# Prepare, with five threads:
a = Always.new(5)
# Start them all together spinning forever with 30-seconds delay between cycles:
a.start do
  puts "I'm alive"
end
# Stop them all together:
a.stop
```

You may be interested to get the backtraces of the exceptions that
happened most recently:

```ruby
# Keep the last 10 error backtraces in memory:
a = Always.new(5, max_backtraces: 10)
# Retrieve them:
p a.backtraces
```

That's it.
